1. Important Precautions
• Never try to take the calculator apart.
• Handle the calculator carefully, and avoid dropping it.
• Do not operate the keys roughly. As you operate the keys,
monitor your input by watching the display to make sure
that values are being input correctly.
• Avoid using the calculator in very hot or cold areas (below 32°F
/ 0°C, or above 104°F / 40°C). Also avoid heavy dust and moisture.
• When using paper, be sure that you install it correctly.
• To clean the calculator, wipe it off with a soft cloth. You can also
clean the exterior by wiping it with a soft cloth that has been
moistened with a weak solution of water and a neutral detergent.
• Never use volatile fluids such as lacquer thinner or benzine, etc.
when cleaning the calculator.
• Be sure to switch the power off after you finish using the calculator
or if you do not plan to use it for a long period. As with all electrical
appliances, it is also a good idea to unplug the power cord from
the AC outlet if you are not going to use the calculator for
a long time.
• Power continues to be supplied to the calculator even when the
Function Selector is in the OFF position. To totally cut power to
the calculator off, unplug the power cord from the AC outlet.
• Whenever you take the calculator to a retailer or dealer for
servicing, we recommend that you remove the paper roll holders,
the tape spools, and all other detachable accessories to keep
them from getting lost.
• Always make sure that roll paper is installed in the calculator
before using any of the Function Selector settings that activates
the printer.

About the input buffer
An input buffer is a place where key operations are temporarily
collected until the calculator can finish the operation it is performing
now and start on the next one. The input buffer of this calculator can
hold up to 12 key operations(both number entries and function
commands), so you can continue key input even while another
operation is being processed.

The printer in this model uses a disposable ink roller (cartridge type).
If impressions are too light or illegible, replace the ink roller with a
new one.
1) Open the printer cover (Fig.A).
2) Remove the ink roller by pulling it up (Fig.B).
3) Install a new ink roller (Fig.C).
4) Make sure the ink roller is in place, and replace the cover.
Note : Never fill the ink roller with fluid ink as it may run or clog the
printer. Use only compatible with IR-40T (Black and Red).

9. Using the Independent Memory
2 decimal places are assumed for entries and results of all
addition and subtraction operations. Entering 2 only results in a
value of 0.02 for the entry. If you use the
key during entry of
a value, the decimal point is included at the place you specify.
This mode has no effect on multiplication and division
operations.
